Description

Technical Field

[0001] The utility model belongs to the technical field of mass spectrometers, and particularly relates to a liquid chromatography-mass spectrometry (LC-MS) instrument for environmental quality detection. Background Art

[0002] A liquid chromatography-mass spectrometry (LC-MS) instrument is an analytical instrument that combines liquid chromatography (LC) and mass spectrometry (MS). Its working principle is as follows: the sample is first separated by liquid chromatography, separating the complex mixture into individual components, and then the separated components are successively introduced into the mass spectrometer for detection and analysis. The LC-MS instrument is a very important analytical tool, providing strong support for fields such as scientific research and quality control.

[0003] However, existing LC-MS instruments also perform environmental quality detection. However, the LC-MS instrument can almost only be used indoors, and the samples to be detected need to be transported to the laboratory through a certain time and distance. During this process, some samples will have problems due to changes in time and temperature, resulting in certain differences in the final detection data. To address the above problems, a LC-MS instrument for environmental quality detection is proposed. Summary of the Utility Model

[0004] To solve the problems existing in the background art, the utility model provides a LC-MS instrument for environmental quality detection, which has better flexibility and an expanded usage scenario.

[0005] The LC-MS instrument for environmental quality detection provided by the utility model includes a LC-MS instrument body. A fixed frame is provided on the lower side of the LC-MS instrument body, and a portable mobile protection component is provided on the fixed frame. The portable mobile protection component includes protective covers symmetrically hinged on the fixed frame. Wheels are symmetrically provided on the protective covers. Symmetrically hinged connections are provided on both sides of the fixed frame with support rods. Positioning blocks are fixedly installed in the protective covers corresponding to the support rods, and the support rods and the positioning blocks fit with each other.

[0006] Further, a plurality of pulleys are provided on the lower side of the fixed frame.

[0007] Further, a control handle is fixedly installed on the protective cover.

[0008] Further, arc-shaped chutes are symmetrically provided on the fixed frame corresponding to the protective covers, and slide rods are fixedly installed on the protective covers corresponding to the arc-shaped chutes. The slide rods are slidably connected with the arc-shaped chutes.

[0009] Further, a clamping groove and a clamping buckle are provided on the protective cover in a matching manner.

[0010] Furthermore, the wheel is disposed on the outer side of the protective cover protruding therefrom.

[0011] Furthermore, a soft material is disposed inside the protective cover.

[0012] Advantages of the present utility model:

[0013] By providing a corresponding mobile protection structure for the mass spectrometry liquid chromatography-mass spectrometry instrument body, the present utility model can move the mass spectrometry liquid chromatography-mass spectrometry instrument body working indoors to the external environment. After the environmental sample sampling is completed, the detection can be quickly carried out, effectively improving the reliability of the overall data detection; the overall mobility and portability are better, and the mass spectrometry liquid chromatography-mass spectrometry instrument body is also protected to a certain extent.
